The difference between straight pins and bent pins for screw terminal block

The solder pin design of screw terminals is usually divided into two types: straight pin and bent pin (Bent Pin or Right-Angle Pin). These two designs differ in installation method, space occupation and application scenarios. Here are their detailed differences:

 

1. Installation direction

 

Straight pin: The solder pin extends in a straight line with the terminal body and is installed perpendicular to the PCB (printed circuit board).

 

Bent pin: The solder pin is bent 90 degrees at the end and installed parallel to the PCB.

 

2. Space occupation

 

Straight pin: Since the solder pin is inserted vertically into the PCB, the terminal body will occupy the vertical space above the PCB.

 

Applicable scenarios: Suitable for applications with sufficient space above the PCB.

 

Bent pin: The solder pin is parallel to the PCB, and the terminal body is parallel to the PCB, occupying less vertical space.

 

Applicable scenarios: Suitable for applications with limited space above the PCB.

 

3. Installation method

 

Straight pin: The solder pin needs to be inserted vertically into the via hole of the PCB, usually used for through-hole technology (THT).

 

Bent pin: The solder pin can be directly soldered on the surface of the PCB, suitable for surface mount technology (SMT) or through-hole technology.

 

4. Mechanical strength

 

Straight pin: Since the solder pin is inserted vertically into the PCB, it has high mechanical strength and can withstand large tension and vibration.

 

Applicable scenarios: Suitable for applications that require high mechanical strength, such as industrial equipment or automotive electronics.

 

Bent pin: The solder pin is connected parallel to the PCB, and the mechanical strength is relatively low, but it can still meet most application requirements under reasonable design.

 

Applicable scenarios: Suitable for occasions where mechanical strength is not required, such as consumer electronics.

 

5. Soldering process

 

Straight pin: Usually wave soldering or manual soldering is used, which is suitable for through-hole insertion technology.

 

Bent pin: Reflow soldering (for SMT) or wave soldering (for THT) can be used, and the soldering process selection is more flexible.

 

6. Heat dissipation performance

 

Straight pin: The solder pin is inserted vertically into the PCB, the heat dissipation path is short, and the heat dissipation performance is better.

 

Bent pin: The solder pin is parallel to the PCB, the heat dissipation path is long, and the heat dissipation performance is slightly worse, but the heat dissipation can be optimized through PCB design.

 

7. Electrical performance

 

Straight pin: Since the solder pin is directly inserted into the terminal block 6 pole, the electrical connection path is shorter and the resistance is lower, which is suitable for high current applications.

 

Bent pin: The electrical connection path is slightly longer, which may increase a small amount of resistance, but the impact can be ignored in most applications.

 

8. Application scenarios

 

Straight pin:

 

Industrial control equipment

 

Automotive electronics

 

Power supply equipment

 

High vibration environment

 

Bent pin:

 

Consumer electronics (such as TVs, audio)

 

Communication equipment

 

PCB design with limited space

 

9. Cost

 

Straight pins: Usually have lower costs because of their simple structure and mature production process.

 

Bent pins: May have slightly higher costs due to the need for additional bending processing.

 

10. Design flexibility

 

Straight pins: The design is relatively fixed and suitable for standardized applications.

 

Bent pins: The design is more flexible and the solder foot direction can be adjusted according to the PCB layout, which is suitable for high-density PCB design.

 

Summary

 

Characteristics Straight Pin Bent Pin

 

Installation Direction Vertical PCB Parallel PCB

 

Space Occupancy Occupies vertical space Saves vertical space

 

Mechanical Strength Higher Lower

 

Soldering Process Wave Soldering, Manual Soldering Reflow Soldering, Wave Soldering

 

Heat Dissipation Better Slightly Worse

 

Electrical Performance Smaller Resistance Slightly Larger Resistance

 

Application Scenarios Industrial, Automotive, High Vibration Environment Consumer Electronics, Communication Equipment, Space-Constrained Design

 

Cost Lower Higher

 

Design Flexibility Lower Higher

 

Choosing a straight pin or a bent pin depends on the specific application requirements, including space constraints, mechanical strength, heat dissipation requirements, and cost.

The Protective Functions of 6 Pin Terminal Block

Introduction:

In modern electrical systems, the proper and secure connection of wires is vital for ensuring safe and efficient operations. One crucial component that facilitates these connections is the 6 pin terminal block. Designed to accommodate multiple wires, these terminal blocks offer various protective functions that enhance the reliability and safety of electrical installations. This article explores the protective capabilities of 6 pin terminal blocks and their significance in electrical applications.

 

Enhanced Connectivity with 6 Way Terminal Blocks:

6 pin terminal blocks, also known as 6 way terminal blocks, provide the ability to connect multiple wires within a single device. Whether it's in industrial machinery, automation systems, or electrical panels, these terminal blocks enable efficient and organized wire connections. The flexibility of the 6-way terminal block design allows for proper routing and management of wires, reducing the risk of short circuits and ensuring optimal electrical performance.

 

Secure Connections with 6 Pin Terminal Blocks:

The primary function of a terminal block is to establish reliable and secure connections between wires. 6 pin terminal blocks excel at this task by providing a robust interface for wire terminations. The secure clamping mechanism of the terminal block ensures that the wires are firmly held in place, preventing accidental disconnections and reducing the chances of electrical faults. Users can rely on the high-quality 6-pin terminal blocks, such as those offered by HOMNECKS, for dependable and durable connections.

 

Protection against Vibration and Mechanical Stress:

In various applications, electrical systems may be subjected to vibration and mechanical stress, which can impact the integrity of wire connections. 6-pin terminal blocks, designed with durability in mind, offer protection against these external factors. The sturdy construction and reliable clamping mechanism of these terminal blocks ensure that the wires remain securely connected, even in demanding environments. This feature enhances system stability and minimizes the risk of intermittent connections or failures.

 

Enhanced Safety Features of 6 Pin Terminal Blocks:

Safety is a top priority in electrical installations, and 6 pin terminal blocks contribute to this goal. With their insulating materials and design, these terminal blocks provide electrical insulation between the connected wires, reducing the risk of electrical hazards, such as short circuits or electrocution. Additionally, some 6pin terminal blocks may feature insulation barriers between adjacent pins, further enhancing safety by preventing accidental contact between wires.
